The using of VPN on iPhone in China [duplicate]

I'd expect that no cross GFWOC (Great Fire Wall of China) traffic is 100% secure from interruption.

2 to 3 years ago I was with a friend who had both a Hong Kong and a Chinese 3G USB modem. The Chinese one was vastly cheaper to use. Well up into Guangjhou the HK one still provided Western Internet access, while the Chinese one never did. We were well beyond single hop cell site range so the HK signal was definitely being relayed through the mainland-Chinese network. This may be a profitable line of investigation. Or not. Chengdu is vastly further in than Guangjhou and they may have their limits on what they allow.

In Shenzhen near the DMZ some hotels have Western capable internet with free WiFi in their public lounges. Whether this facility is available deep in the interior I know not.

Chinese internal internet is horrendously broken by the Great Fire Wall of China. Things that you take for granted either just don't work or walk funny or you get routed to "equivalent services" when you try to use familiar sites. Do not believe shilling apologists who for whatever reason tell you otherwise - unless they have change it all majorly since December 2012 when I was last there.

Superb solution: I got superb results using Team Viewer.
I used version 7 but they now have version 8 available.

I used it from a netbook in China to a LAN in NZ but I imagine that they have iPhone capability. The program effectively gives you the ability to remote control a distant system rather than just to tunnel through the GFWOC and it may not directly suit the mode of operation that you had in mind. It did what it did do in an incredibly capable manner. Remote access to all PCs on a LAN (my wife was impressed (takes some doing with boring things like PCs ) when I freed up space on the WifI connected netbook she was using in NZ while I was sitting in a hotel room in China :-). , file transfer both ways, access to my barred GMail account (not to mention Facebook, Wikipedia, Wikimapia, ...), excellent screen update choices with balance movable between quality and speed. I've used remote control software before but nothing was ever this good.

As I recall, browser operation without install on your local PC BUT you can also leave a sleeping kernel on PCs so that you can access them remotely subsequently.

It is free to download free for non-commercial use and apparently very unconcerned about stopping you using it. It reminds you very pointedly at each startup that if you are using it for commercial use then you need a licence, but it places no restrictions on functionality or length of use.

I'm not sure where the commercial / private boundary is - they are not very specific. I used it when I was absolutely stuck and it made a vast difference to my ability to call home. I was unsure if I qualified as a free user - the friend who recommended it to me has used it with gay abandon for years in all his Chinese business dealings. He assures me he does not match their definition. I'm not so sure.

Pricing seems a bit hard to fathom - they seem to be aiming at corporates, but the cost per user seemed exceptionally high, alas. (Around $1000/user as I recall - if anyone finds that it's $10 do come back and tell me).
